What Causes the Windshield to Not Be Cleaned Properly?

[AshlynRose]

The reasons why the windshield cannot be cleaned properly are: 1. The wiper blades are aged; 2. The glass surface is corroded. A wiper is a blade structure installed in front of the windshield, composed of a motor, reducer, four-link mechanism, wiper arm spindle, and wiper blade assembly. Its function is to remove rain, snow, and dust that obstruct the view on the windshield. The method for removing and installing the wiper is: 1. Lift the metal wiper arm from the windshield and keep it stable in a position perpendicular to the windshield; 2. Press the buckle to remove the old wiper blade, separate it from the metal arm, then insert the new wiper and rotate it until the hook snaps into place and is secured; 3. Place the wiper back onto the windshield.
